Method and apparatus for transmitting or receiving data in wireless communication system

Abstract

The present disclosure includes a method, performed by a terminal, of using a location-based service. The method includes: receiving, from a base station, a radio resource control (RRC) message including protocol information related to a location of the terminal; obtaining location-related information of the terminal based on the RRC message; and transmitting, to the base station, a response message including the location-related information, wherein the protocol information is generated by a first location management function (LMF) having a logical connection inside the base station or a second LMF located in a core network, based on request information for a location-based service received from a client server.

1 . A method, performed by a terminal, of using a location-based service, the method comprising:
 receiving, from a base station, a radio resource control (RRC) message comprising protocol information related to a location of the terminal;   obtaining location-related information of the terminal based on the RRC message; and   transmitting, to the base station, a response message comprising the location-related information,   wherein the protocol information is generated by a first location management function (LMF) having a logical connection inside the base station or a second LMF located in a core network, based on request information for a location-based service received from a client server.   
     
     
         2 . The method of  claim 1 , wherein the protocol information is generated by the first LMF when the terminal is RRC-connected to the base station or is in an inactive state, and generated by the second LMF when the terminal is in an idle state. 
     
     
         3 . The method of  claim 1 , wherein the RRC message comprises an indicator corresponding to an LMF that generates the protocol information, or comprises the protocol information in an information element (IE) that varies according to the LMF. 
     
     
         4 . The method of  claim 3 , further comprising determining which LMF from among the first LMF or the second LMF generates the protocol information, based on the RRC message,
 wherein the response message is generated to comprise the indicator, or to comprise the protocol information in the IE.   
     
     
         5 . A method, performed by a base station, of providing a location-based service, the method comprising:
 receiving, from an access management function (AMF), request information for a location-based service;   receiving protocol information on the request information from a first location management function (LMF) having a logical connection inside the base station;   transmitting a radio resource control (RRC) message to a terminal based on the protocol information;   receiving, from the terminal, a response message comprising location-related information of the terminal, based on the RRC message; and   transmitting the response message to the AMF.   
     
     
         6 . The method of  claim 5 , wherein the request information comprises identification information on the terminal, or information on the base station to which the terminal connects. 
     
     
         7 . The method of  claim 5 , wherein the RRC message comprises an indicator corresponding to the first LMF, or comprises the protocol information in an information element (IE) corresponding to the first LMF. 
     
     
         8 . A terminal for using a location-based service, the terminal comprising:
 a transceiver; and   at least one processor connected to the transceiver and configured to   receive, from a base station, a radio resource control (RRC) message comprising protocol information related to a location of the terminal,   obtain location-related information of the terminal based on the RRC message, and   transmit, to the base station, a response message comprising the location-related information,   wherein the protocol information is generated by a first location management function (LMF) having a logical connection inside the base station or a second LMF located in a core network, based on request information for a location-based service received from a client server.   
     
     
         9 . The terminal of  claim 8 , wherein the protocol information is generated by the first LMF when the terminal is RRC-connected to the base station or is in an inactive state, and is generated by the second LMF when the terminal is in an idle state. 
     
     
         10 . The terminal of  claim 8 , wherein the RRC message comprises an indicator corresponding to an LMF that generates the protocol information, or comprises the protocol information in an information element (IE) that varies according to the LMF. 
     
     
         11 . The terminal of  claim 10 , wherein the at least one processor is further configured to determine which LMF from among the first LMF or the second LMF generates the protocol information, based on the RRC message,
 wherein the response message is generated to comprise the indicator, or to comprise the protocol information in the IE.   
     
     
         12 . A base station for providing a location-based service, the base station comprising:
 a transceiver; and   at least one processor connected to the transceiver and configured to   receive, from an access management function (AMF), request information for a location-based service,   receive protocol information for the request information from a first location management function (LMF) having a logical connection inside the base station,   transmit, to a terminal, a radio resource control (RRC) message based on the protocol information,   receive, from the terminal, a response message comprising location-related information of the terminal, based on the RRC message, and   transmit the response message to the AMF.   
     
     
         13 . The base station of  claim 12 , wherein the request information comprises identification information on the terminal, or information on the base station to which the terminal connects. 
     
     
         14 . The base station of  claim 12 , wherein the RRC message comprises an indicator corresponding to the first LMF, or comprises the protocol information in an information element (IE) corresponding to the first LMF. 
     
     
         15 . The base station of  claim 12 , wherein the terminal is RRC-connected to the base station or is in an inactive state.
